The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0029] As Figures 1 to 4 shown, a spraying machine with adjustable spraying range of the present utility model includes: a base 1, a paint tank 2, the paint tank 2 is fixedly installed on the top of the base 1, a nozzle seat 10, a mixing mechanism for mixing the paint in the inner cavity of the paint tank 2, and an adjusting mechanism for adjusting the spraying range.

[0030] The mixing mechanism includes: a longitudinal mixing component for longitudinally mixing the paint in the inner cavity of the paint tank 2, and a transverse mixing component for transversely mixing the paint in the inner cavity of the paint tank 2; the longitudinal mixing component includes: a pump body 3 fixedly installed on the paint tank 2, a feed pipe 4 and a return pipe 5 communicated with the pump body 3, the other ends of the feed pipe 4 and the return pipe 5 are both communicated with the paint tank 2, and a first solenoid valve is installed on the return pipe 5; the transverse mixing component includes: a rotating shaft rotatably installed in the paint tank 2, a fan blade 12 and a stirring blade 13 fixedly installed on the paint tank 2; a telescopic hose 11 is communicated between the pump body 3 and the nozzle seat 10, and a second solenoid valve is installed on the telescopic hose 11.

[0031] When mixing the paint in the inner cavity of the paint tank 2, the second solenoid valve is closed, the first solenoid valve is opened, and by starting the pump body 3, the paint in the inner cavity of the paint tank 2 can be sucked out through the feed pipe 4 and refluxed into the inner cavity of the paint tank 2 through the return pipe 5, so as to realize the longitudinal mixing of the paint, and further ensure that the paint is evenly distributed in the longitudinal direction during the mixing process, enabling the paint components at different levels to be fully contacted and mixed, reducing the concentration gradient in the paint, making the distribution of the paint components more uniform, and thus improving the overall performance of the paint.

[0032] When the coating flows back into the coating tank 2 through the return pipe 5, it is sprayed on the fan blade 12, which can drive the fan blade 12 to rotate. The fan blade 12 drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade 13 to rotate. Through the rotation of the stirring blade 13, the transverse mixing of the coating can be realized, so as to ensure that the components such as pigments, fillers, and additives in the coating are fully mixed in the transverse direction, break the agglomeration state of pigment particles, and improve the overall uniformity of the coating.

[0033] Through the settings of the longitudinal component and the transverse component, the coating is mixed horizontally and longitudinally, improving the coating mixing efficiency, making the distribution of coating components more uniform, thus improving the overall performance of the coating, and solving the problem that when the existing spraying machine mixes the coating in the coating tank 2, only the horizontal stirring method is used to realize the mixing of the coating, which is easy to cause uneven mixing and affect the spraying effect.

[0034] When the coating is mixed evenly, the first solenoid valve is closed and the second solenoid valve is opened at this time, so that the coating flows into the telescopic hose 11 and is sprayed out through the nozzle seat 10, thereby realizing the spraying operation.

[0035] The adjusting mechanism includes: a horizontal adjusting component for adjusting the horizontal angle of the nozzle seat 10, a lifting component for adjusting the height of the nozzle seat 10, and a pitching adjusting component for adjusting the pitching angle of the nozzle seat 10; the horizontal adjusting component includes: an installation box 6 fixedly installed on the top of the base 1, a motor 14 fixedly installed in the inner cavity of the installation box 6, a driving gear 15 fixedly connected to the power output shaft of the motor 14, a rotating rod 17 rotatably installed on the installation box 6, and a driven gear 16 fixedly sleeved on the rotating rod 17; the driving gear 15 and the driven gear 16 are meshed with each other.

[0036] By starting the motor 14, the motor 14 drives the driving gear 15 to rotate. Since the driving gear 15 and the driven gear 16 are meshed with each other, the driving gear 15 drives the driven gear 16 to rotate, and the driven gear 16 drives the rotating rod 17 to rotate, thereby driving the nozzle seat 10 to rotate horizontally, so as to realize the adjustment of the horizontal angle of the nozzle seat 10.

[0037] The lifting component includes: a connecting pipe 7 fixedly installed at the top end of the rotating rod 17, a movable pipe 8 movably installed in the connecting pipe 7, and a first cylinder 18 fixedly installed between the connecting pipe 7 and the movable pipe 8.

[0038] By starting the first cylinder 18, the first cylinder 18 drives the movable pipe 8 to move in the inner cavity of the connecting pipe 7, so as to adjust the overall height of the connecting pipe 7 and the movable pipe 8, and further realize the height adjustment of the nozzle seat 10.

[0039] The pitch adjustment assembly includes: a mounting plate 9 fixedly installed at the top end of the movable pipe 8, and a second cylinder 19 hingedly installed between the mounting plate 9 and the nozzle seat 10; the nozzle seat 10 is hingedly installed on the mounting plate 9.

[0040] By starting the second cylinder 19, the nozzle seat 10 can be driven to rotate around the hinge point between the nozzle seat 10 and the mounting plate 9, thereby realizing the pitch angle adjustment of the nozzle seat 10.

[0041] Through the setting of the adjustment mechanism, it is convenient to adjust the horizontal angle, height, and pitch angle of the nozzle seat 10, thereby realizing the adjustment of the spraying range of the nozzle seat 10, and further improving the applicability and working efficiency of the spraying machine.

[0042] Universal wheels are fixedly installed at the bottom of the base 1, and a push rod is fixedly installed at the top of the base 1. Through the setting of the universal wheels and the push rod, it is convenient to push the spraying machine to move, improving the flexibility of the spraying machine.

[0043] Working principle: During use, when mixing the paint in the inner cavity of the paint tank 2, the second solenoid valve is closed and the first solenoid valve is opened. By starting the pump body 3, the paint in the inner cavity of the paint tank 2 can be sucked out through the feed pipe 4 and returned to the inner cavity of the paint tank 2 through the return pipe 5, thereby realizing the longitudinal mixing of the paint. Furthermore, it can ensure that the paint is evenly distributed in the longitudinal direction during the mixing process, enabling different layers of paint components to come into full contact and mixing, reducing the concentration gradient in the paint, making the paint component distribution more uniform, and thus improving the overall performance of the paint; when the paint flows back to the paint tank 2 through the return pipe 5, it sprays on the fan blades 12, thereby driving the fan blades 12 to rotate. The fan blades 12 drive the rotating shaft to rotate, and the rotating shaft drives the stirring blades 13 to rotate. Through the rotation of the stirring blades 13, the transverse mixing of the paint can be realized, thereby ensuring that components such as pigments, fillers, and additives in the paint are fully mixed in the transverse direction, breaking the agglomeration state of pigment particles, and improving the overall uniformity of the paint; through the operation of the longitudinal component and the transverse component, the paint is mixed horizontally and longitudinally, improving the paint mixing efficiency, making the paint component distribution more uniform, and thus improving the overall performance of the paint, solving the problem that the existing spraying machine only realizes the mixing of the paint in the paint tank by means of transverse stirring, which is likely to cause uneven mixing and affect the spraying effect; when the paint is mixed evenly, at this time the first solenoid valve is closed and the second solenoid valve is opened, so that the paint flows into the telescopic hose 11 and is sprayed out through the nozzle seat 10, thereby realizing the spraying operation.
